What Is a Public Cloud?

public cloud

The most common cloud computing model is the public cloud. In this model, the services are constructed using shared physical resources pooled together and provided in a virtual environment. The client can access this using a public network like the Internet.

In public clouds, services can be provided to several clients at the same time, even while using the same infrastructure. Private clouds, on the other hand, the services are offered to only one client at a time, with the computing resources being exclusive to that one client.


Most cloud computing can be categorized as public cloud model. This is because cloud computing, in general, is publicly available. Some examples include:

Public clouds are perfect for the consumers who do not need the high levels security as well as infrastructure that go along with private clouds.

Despite this, public clouds are still be a useful choice for enterprises. Public clouds can be used as storage for unimportant, less sensitive data such as webmail or collaborations on online documents.

Features and Benefits

The Ultimate Scalability

The public cloud itself is a massive pool of computing resources from which clients can infinitely get from to ensure that the applications they are running will run flawlessly despite any fluctuations in usage.

High Cost Efficiency

These clouds work in a centralized system while the management of the resources underneath is divided among the many different cloud services. Additionally, the components, like the servers, do not need as much customization on the provider’s part. All this means that public clouds can pool together the greatest levels of resources which allows it to benefit heavily from economies of scale.

Easy Payment Model

These clouds commonly utilize the pay-as-you-go method of payment, wherein the customer is given the right to use any resources they need whenever they want, and they will only have to pay for the resources they used.

Highly Reliable

There is an enormous number of networks as well as servers that are involved in the system of a public cloud. Combined with the custom configurations that emphasizes heavily on redundancy means that the servers would very rarely have any down time; a failure of a single physical component will hardly affect the providing of the cloud service.


There is a great number of SaaS, IaaS, and PaaS services that are currently available, and all of them utilize the public cloud model. All of these services can also be accessed readily using any device with internet access. All these servers are equally capable of fulfilling the average computing requirements and are capable of catering to private clients as well as enterprises.

Independent on Location

The services of this type of cloud can be accessed using the internet, meaning you can access them as long as you have an internet connection regardless of your location. This is a useful feature that can allow for various uses such as allowing people to collaborate on a single document regardless of the geographic challenges.
